We're dividing 87116020 by 125 
The aim is to understand the frequency of 125 in 87116020.

Let's proceed to step 1:
8 divided by 125 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 125

Let's proceed to step 2:
If we divide 87 by 125, we get 0 and a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Fetch the next digit (1) from the dividend, attach it to 87 and continue: 871 / 125

Step 3:
If we divide 871 by 125, we get 6 and a remainder of 121.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 750 away from 871, we end up with 121.
Append the next digit (1) from the dividend to 121 and continue with: 1211 / 125

Advancing to step 4:
When dividing 1211 by 125, we get 9 with a remainder of 86.
Put 9 as the next digit of the answer. 
Result so far: 69.0
If we subtract 1125 from 1211, we get 86.
Take the next digit (6) from the dividend and append it to 86, then repeat: 866 / 125

Let's proceed to step 5:
When dividing 866 by 125, we get 6 with a remainder of 116.
Use 6 as the next digit of our solution. 
Result so far: 696.0
If we take 750 away from 866, we end up with 116.
Grab the next digit (0) from the dividend, add it to 116, then carry on: 1160 / 125

Moving on to step 6:
If we divide 1160 by 125, we get 9 and a remainder of 35.
The number 9 becomes the next digit in our result. 
Result so far: 6969.0
The remainder is 35 after subtracting 1125 from 1160.
Fetch the next digit (2) from the dividend, attach it to 35 and continue: 352 / 125

Advancing to step 7:
If we divide 352 by 125, we get 2 and a remainder of 102.
Write down 2 as next digit of the result. 
Result so far: 69692.0
Subtract 250 from 352 to get 102.
Fetch the next digit (0) from the dividend, attach it to 102 and continue: 1020 / 125

Step 8:
125 goes into 1020 8 times with a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 696928.0
Subtracting 1000 from 1020 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
When dividing 200 by 125, we get 1 with a remainder of 75.
Use 1 as the next digit of our solution. 
Result so far: 696928.1
The remainder is 75 after subtracting 125 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 10:
125 can be fit into 750 6 times, resulting in a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 696928.16
Subtracting 750 from 750 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
The number 125 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 696928.16
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 12:
The number 125 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 696928.16
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 696928.16, with a leftover of 0.0.
